ABSTRACT:
In a gas turbine engine including a compressor having a casing with a passage adapted to pass bleed air to a circumferentially extending bleed manifold surrounding the casing, the passage including a surface exposed to incendiary particles periodically entrained in the bleed air, an improvement is provided comprising means for preventing impingement of the particles upon the exposed surface. In one form the means is disposed between the exposed surface and the bleed air and is comprised of a material which, when reacted with the particles, produces a compound which is essentially nonpyrophoric in the environment of the passage.
